05/04/2025 First of all, we love our Avalon. However, for the last 6 months or so, water is getting in the car and ends up soaking the carpet on the left front floorboard carpet. We have checked everything we can think of to find the source of the leak but was uneasily. We had to have some scratches fixed and took the car to a body shop to see if they could find the source of the leak. They sprayed water on the sunroof for about an hour but no water leaked inside. We have also taken the car to the local Toyota Dealership (Sheehy Toyota in the Fredericksburg area, they could not find the source of the leak. It rained here (Fredericksburg, VA last night and the left front floorboard was soaked. I need help finding the source of the leak(s) so we can continue enjoying our Avalon. Any help would be appreciated. Thank you, [XXX] [XXX] Phone number [XXX] (cell phone) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving the pre-collision system (PCS) turns on unexpectedly, without any warning lights or sounds, and applies the brakes. This happens when I am driving in traffic with plenty of space between the car in front of me. I typically drive between 3-6 seconds behind the car in front of me to allow for at least 300 feet in space when driving at highway speeds. Despite leaving plenty of room for cars in front of me, on multiple occasions the car has started braking abruptly while going anywhere between 50, 40, 30, or 20 miles per hour. This can be verified for inspection upon request. Despite there being a recall for my specific year, make, and model car (2015 Toyota Avalon) for this exact issue my VIN number is not covered. Toyota is requiring me to pay out of pocket for them to 1) determine if its malfunctioning and 2) replace the system, which is a huge conflict of interest. Even though the Driver's Manual says that I can disable the PCS by clicking on the PCS on/off button within the driver's glovebox, there is no such button, only a blank button cover. Not having the ability to disable the PCS system, or worse, allowing it to continue braking while I'm driving is a serious hazard. The car can start braking while I am accelerating to merge onto expressway on-ramps, or while changing lanes at the same speed of traffic. The car can also unexpectedly brake while cars are traveling too close behind me. I want to know why my VIN was not included in the initial recall and why I now have to pay to have it looked at or repaired when its clearly malfunctioning and can't be turned off as the Driver's Manual says it can. I should not have to pay $175 an hour for several hours for a Toyota dealership to diagnosis it and then another $175 an hour for 2.5 hours for them to install the fix and whatever the new component costs. I recently bought this car at 35,500 miles and the issue immediately started occurring just as the warranty expired at 36,000 miles.

I have a safety concern. I bought a new car a couple of weeks before this incident; this is what I experienced with the pcs system. It went off with warning buzzer, retracting the seat belts. To my surprise, the frontal car was more than 120 to 150 feet away!; I believe I was driving at about 50-55 MPH. Since this is my first experience with the pcs system, I am not sure if this was normal or whether I should bring the car in for inspection. I took the car to the dealer; they gave me a toyota case no. 152660366 ; mechanic said he performed health check on the vehicle and passed. I have not heard from either the dealer nor the manufacturer since then. Please advice. Additional info: vehicle in motion about 50 MPH, city street driving, straight broad
